Topic: skilled motor learning

Prompt execution of planned motor action is context-dependent and a critical component of animal behavior. Studies from humans, non-human primates, and rodents have ubiquitously established that the primary motor cortex (M1) is the main hub for skilled motor learning, which relies on the precise coordination of multiple brain regions. Yet, how various populations of neurons separated by millimeters reliably communicate is still unclear. Here, we investigate how moment-to-moment and trial-to-trial fluctuations of population dynamics in the secondary (M2) motor cortex relate to stable population
